Targeted at media reports that "large-capacity battery laptop battery security risks can not be ignored", will the Gentile CATR laboratory-related experts, ultra-long standby laptop battery is a trend, but, at the present level of technology, the battery capacity not be much higher, 2000 mAh more than the best cell phone batteries for large-screen laptop, or deposit security risk.

At present, the phone functions continuously enriched, MP3, MP4 laptop, camera, GPS navigation capabilities increasing laptop standby time consumer demand is increasing. There are many ways to improve standby time, the most direct is to enhance the battery capacity. Currently hot home-made laptops in the market, in the TV shopping ads crazy bombing, the overwhelming are ultra-long standby, large amounts of information, these are all large-capacity battery is bulky batteries. Large volume of high-capacity battery now seems to have become a selling point for China-made dell 2834T battery laptops.

In this regard, there are media reports said that "the continuous improvement of battery capacity, along with the battery of the security risks has increased. Lithium battery is a positive, negative, diaphragm, electrolyte such as material composition, lithium battery is chemical energy into electrical energy device, this conversion is directly through the electrochemical oxidation and reduction reaction to completion. Please note that this is a redox reaction, a typical chemical reaction, inherent instability. "

On this issue, we specifically tested the responsible dell Latitude LS battery authority on laptops CATR CTTL consulting, Gentile laboratory-related, experts said, ultra-long standby laptop is a trend that's for sure, the current PDA phones the use of ultra-long standby laptop batteries, 3G laptop business in the future more, 3G laptop has the need for large capacity battery.

However, the experts said that the current ultra-long standby technology is not yet very mature, not suitable for ordinary laptops, is only suitable for large-screen laptop.

The expert explained that the ultra-long standby laptop batteries are bulky, can not do the volume is still small, if the cell phone to give it enough space for the volume, it can be done well, no safety problems, but afraid installed in an ordinary cell phone to cell phone batteries can not be too much space.

In addition, the ultra-long standby laptop batteries, there are two, one is the battery electric decompression theory, a theory of polymer battery, two batteries dell Inspiron 2000 battery are widely applied, mainly extract the principle of super-capacity electric batteries keep hidden.

Previous reports the main point the finger of blame over 2000 mAh long standby battery that is currently in the 2000 mAh batteries and the following battery models through the large-scale production, technology and processes have been very mature, quality and safety is guaranteed; However, over-capacity battery 2000 mAh batteries dell W0465 battery, the current technology and craft are not very mature, there is a great big security risk.

In this regard, the experts said, at present, ultra-long standby laptop battery by CATR laboratory testing are also many Gentile, 3000 mAh, 4000 mAh of both, but is indeed a 2000 mAh following technology is relatively mature , in particular the 1200 mAh following very mature, 2000 mAh or more are often tailor-made laptop manufacturers, laptop battery is not yet a mainstream product. Manufacturers in the use of more than 2000mAh batteries when the current process should be carefully dell Latitude X300 battery considered to avoid the less mature processes result in security vulnerabilities.
